    <p>Currently, I use the following regular expression to parse sentences in a document:</p> <pre><code>Pattern.compile("(?&lt;=\\w[\\w\\)\\]](?&lt;!Mrs?|Dr|Rev|Mr|Ms|vs|abd|ABD|Abd|resp|St|wt)[\\.\\?\\!\\:\\@]\\s)"); </code></pre> <p>This almost works. For example: Given this string:</p> <p>"Mary had a little lamb (i.e. lamby pie). Here are its properties: 1. It has four feet 2. It has fleece 3. It is a mammal. It had white fleese. Her father, Mr. Lamb, lives on Mulbery St. in a little white house."</p> <p>I get the following sentences:</p> <pre><code>Mary had a little lamb (i.e. lamby pie). Here are its properties: 1. It has four feet 2. It has fleece 3. It is a mammal. It had white fleese. Her father, Mr. Lamb, live on Mulbery St. in a little white house. </code></pre> <p>However, what I would like is:</p> <pre><code>Mary had a little lamb (i.e. lamby pie). Here are its properties: 1. It has four feet 2. It has fleece 3. It is a mammal. It had white fleese. Her father, Mr. Lamb, lives on Mulbery St. in a little white house. </code></pre> <p>Is there anyway to do this by altering the existing regular expression? </p> <p>Right now to accomplish this task, I first do an initial split and then check for bullets. The following code works but I'm wondering if there is a more elegant solution:</p> <pre><code>public static void doHomeMadeSentenceParser(String temp) { Pattern p = Pattern .compile("(?&lt;=\\w[\\w\\)\\]](?&lt;!Mrs?|Dr|Rev|Mr|Ms|vs|abd|ABD|Abd|resp|St|wt)[\\.\\?\\!\\:\\@]\\s)"); String[] sentences = p.split(temp); Vector psentences = new Vector(); Pattern p1 = Pattern.compile("\\b\\d+[.)]\\s"); for (int x = 0; x &lt; sentences.length; x++) { Matcher matcher = p1.matcher(sentences[x]); int bstart = 0; boolean bulletfound = false; while (matcher.find()) { bulletfound = true; String bullet = sentences[x].substring(bstart, matcher.start()); if (bullet.length() &gt; 0) { psentences.add(bullet); } bstart = matcher.start(); } if (bulletfound) psentences.add(sentences[x].substring(bstart)); else psentences.add(sentences[x]); } for (int x = 0; x &lt; psentences.size(); x++) { String s = (String) psentences.get(x); System.out.println(s.trim()); } } </code></pre> <p>Thanks in advance for any help.</p> <p>Elliott</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
